As the OPs stated, hard to give too much input without more information. Was at Copper yesterday, still thin in spots, especially if you are looking for ungroomed runs. With a couple more storms, most of the frontside blue and green runs should be open by the time of your stay. A-Lift, Resolution bowl, and Union bowls are not guaranteed to open by then and Spaulding and Copper Bowls being open is most unlikely.
I'll be at Copper on the 14th and 19th. I would be happy to ski with you or at least point some areas out that you might enjoy. Send me a PM if you want to meet up.
Enjoy you vacation.
